To all whom, it may concern: triangular form illustrated in the drawings, so Be it known that I, ELISHA O. HUSSEY, a that when its outer portions are adapted to citizen of the United States, and a resident of the saw-kerfs a in the vertical and horizontal Philadelphia, Pennsylvania, have invented bars A of the frame aportion of the strip will certain Improvementsin Frames for Windowextend across from one bar to the other and Screens, &c., of which the following is a speciwill form a corner brace or bracket for the fication. frame, thus not only materially adding to the The object of my invention is to furnish carstrength of the frame at the joint, but impenters and others with screen-frame stock of parting to said frame at the corners the or- To such character that strong and neat screens of namental finish desirable in this class of work. any desired dimensions may be readily made The tenon-strips may be secured to the bars therefrom Without the exercise of any particuof the frame by means of brads, screws, dowellar skill.

In carrying out myinvention I provide bars the only operations to be performed are the A of the proper width and thickness for the sawing of the bars to length and fastening bars of the frame to be constructed, and prefthemand the tenon-strips together. As the 2 5 erably of the maximum length for-the length tenon-strips are preferably of wood and are and height of the particular grade of screen necessarily comparatively thin, it becomes a for which they are intended.

2. The combination of the vertical and horizontal bars of the frame, having their inner faces mortised at the meeting ends, with the wooden corner-pieces, one edge of which is secured to the vertical bars and the other edge projecting beyond the ends of the said vertical bars and sliding in and adapted to be secured in the groove of the horizontal bars, and havingthe grain running at an angle both to the vertical and horizontal bars of the frame, as and for the purpose set forth.
